Cross Hatch Adhesion Tester

Cross Hatch Adhesion Tester or Adhesion Testers verify that both surface preparation and coating application are within specification.

From the largest man-made structures to the smallest household appliances, most manufactured products have a protective or cosmetic coating. Premature failure of this coating can, at the very least, result in additional costs of rework.

Adhesion testing after the coating process will quantify the strength of the bond between substrate and coating, or between different coating layers or the cohesive strength of some substrates. Routine adhesion testing is used as part of inspection and maintenance procedures to help detect potential coating failures.

Using this Cross Hatch adhesion tester is a fast, low cost, visual comparison method for paint and powder coatings up to a thickness of 250µm in order to evaluate the coating adhesion. The coating is cut into small squares, thereby reducing lateral bonding, and the coating adhesion assessed against ISO, ASTM or Corporate Standards.

Applications – For paint and powder coatings up to a thickness of 125mic

Product Description

The coating may be continuous and look good, but how well is it connected to the substrate? The Elcometer 107 Cross Hatch Cutter provides an instant assessment of the quality of the bond to the substrate, commonly used on flat test panels.

Due to its rugged construction this cross hatch gauge is ideal for thin, thick or tough coatings on all surfaces. An ideal field or laboratory test.

Product Description

The Elcometer 1542 Cross Hatch Adhesion Tester is a simple but effective tester to determine the adhesion of coatings. This instrument is ideal for coatings on flat surfaces and is available with one of three different spacings:

Product Description

The Elcometer 1540 Cross Cut Tester is a simple instrument for quickly determining the adhesion of a large variety of paints up to 50µm thickness. Made from steel, it has 11 tapered teeth with 1mm spacing. Two sets of lines are cut at right angles to obtain a pattern of 100 squares. Results are determined by the table below.Read More
